Senior Software Engineer

Job description

At NI IP Routing SW, we believe in fostering a flat and non-hierarchical work environment. We are obsessed about delivering high-quality products and ensure the utmost level of excellence in everything we do. We are a passionate bunch and strive to be technological leaders in our industry. You will be integral to a close-knit team to engineer best-in-class products for the most critical networks – data centers for web/hyper-scalers, telcos and enterprises (including AI fabrics), and communication service provider networks.

We are looking for SW engineers who wish to be a part of developing and evolving the current and next generation of routers that form the core of anything internet. These routers are at the heart of Nokia’s IP product offerings, from data centers (including AI fabrics) to providing strong, resilient low latency and dependable IP backhaul for service providers and mission critical networks. In this role, you will have the opportunity to work with one of the best engineering teams in the industry.

We value your expertise and offer an environment where you can thrive both professionally and personally. There are more customers we want to win, more networks to penetrate, more technologies to enable and more applications to support. We want to make smaller products, and we want to make bigger products. We want to build products based on newer standards and newer ASICS in the market. You will play a critical role in designing and implementing high-performance data path solutions on both custom and merchant silicon.

You will be responsible for writing efficient and modular code that is well-tested and robust, ensuring that it meets the high standards required for the most critical networks. Your role will involve working on advanced packet forwarding techniques in IP, MPLS, Segment Routing, VxLANs. You will also contribute into Traffic Management technologies - QoS (Policers, Schedulers, Shapers), ACLs, TCAM Management, and Packet Extractions to CPU.
